I recall there was a sort of war scare, or maybe a 'war excitment' in 1907 in the US concerning Japan. If this actually does come to war what is Britains attitude then?
 
I'm afraid imperializing Japan was against our interests, because it was way far and too populated for easy empire. And we had our own treaty, from our Perry Expedition.

OTL TR and Taft were buddies with Japan in their empire in Korea; Taft even went on a state visit to Japan.

Sorry.
 
Anytime between the signing of the Anglo japanese alliance and world war 1 . Had the us and an other power declared war on Japan for whatever reason would britian honor their alliance or abandon their ally for better relations with the U.S.

I answered no.

But to declare war on the Japan that defeated Russia, the USA is first going to need a strong investment in its navy.

The Great White Fleet had sixteen pre-dreadnaught battleships, all of them less than ten years old. I think the US has that covered.

How much would having the British & the commonwealth neutral in a Pacific war help the Japanese?

As aside if you want a power to join in with the US perhaps French are a good option?
 
Would an Anglo-American war mean an invasion of Canada? How would that go down?


Depends.

1. Starting from the usual unprepared American position probably an bloody mess for months until a mass army is formed that is just too much.
2. There is a build up too war and serious political will for a strong military probably leaves Canada occupied in short order.

The British had critically decided to leave Canada to its fate but whether they would actually do so is another matter but the 10:1 population disparity is a big issue for any North American war.
 
The British nitrate monopoly ended in 1913 (thank you Germany). Its hardly a coincidence that the Central Powers felt safe to release the hounds just year year later.

A US DoW/attack on Japan is a total non-starter. Too pro-Japanese until after WWI. Too Isolationist in the midwar period due to the shock of losses in WWI and the economic devastation of the Great Depression.

For Japan to be crazy enough to attack the USA you'd need their relatively desperate circumstances of 1941 + a maximized IJN + a distracted Alliance and USA.

Politically, a war with the British Empire post-WWI would also be a non-starter. Or frankly at anytime post-American Civil War. The British had already set themselves on a Pro-American neutral policy that early, and would continue to do so until Pearl Harbor ignited the Special Relationship for good. If the USA for whatever reason launched an unprovoked attack against Japan (hello Skippy), the British would probably launch a trade embargo against the USA, as well as offer mediation. Such an attack by the USA would leave America deeply divided and prone to a rout for the government at the next election once the battle results come in regarding when the overconfident yanks engage "those little near-sighted yellow bastards".

In 1900, UK had 14.6% of World Trade, USA 14.1% Canada 1.6% and Japan 1%.

I just don't see an embargo getting thru Parliament, unless it's an all out attack on Canada, not Japan.
 
Not a chance. To be frank, a neutral Inited States is more important to British interests than an allied Japan.
 
War--difficult...

At that time, I don't think Britain would risk losing Canada--that is just so much more valuable than anything that the British might take from the USA. And if the USA was determined, Canada would most likely fall. (Any war that had Britain seriously committed elsewhere would likely see France or Germany fishing in troubled waters...)

I can see one way that Japan could attempt to neutralize the USN in one fell swoop...go after the Great White Fleet in a surprise attack as it was visiting Japan. That would, however, really poss off everyone, and I think Britain would be smart enough to stay away from the mayhem...

All the second point would cause is TR making his own version of his nephew's day of infamy speech, and Britain will drop Japan in an instant. It won't be quite as bad as post-WWII Japan, but it would still be pretty bad...
 
It depends on the circumstances, but I think it's far more likely that Britain would offer to mediate a pre-WWI conflict between the US and Japan.

Agreed. Mediation. Unless it's a Pearl Harbor, in which case the Empire drops Japan like a hot rock and someone else offers mediation. France? Germany?
 
No mediation here..

If it's a surprise attack, would anyone offer mediation? And would the USA be interested in anything at all livable for Japan? There's no chance, at this time, of invading Japan, but, I feel confident that, with motivation, the US could develop a fleet train capable of long range operations.
 
Without the mandates can the IJN stop the US just steaming to the PI and building a fleet base to threaten the home islands ?

Do you need a fleet train when you can then go PI-Formosa-Okinawa-Japan ?

If Japan were to ambush and destroy the Great White Fleet (say the Treaty of Portsmouth doesn't turn out as well for Japan-the OTL terms damaged American-Japanese relations-and the Japanese go crazy and decide on revenge and seek "compensation" in the Philippines) Great Britain would drop Japan like a rock. I doubt the British would even try to mediate and would just get out of the Americans' way. By 1912 the Japanese get hit in the face by a dozen South Carolinas, Delawares, and Floridas while an American-subsidized Russian army storms into Korea.

The above though would require a lot more work to make it not ASB.


Now if the US decided for some reason to declare war on Japan things become different. However if the UK joined in on the Japanese side it wouldn't surprise me if the Canadians decide they don't feel like fighting the country to their south that outnumbers them 10 to 1 to protect the Japanese and tell the UK to get stuffed.
